Once placed, the C4 item in the player's inventory will be replaced by the C4 remote. Upon right-clicking with the C4 remote, the C4 will explode, doing a high amount of damage. Left-clicking with the C4 remote will allow the player to place more C4. This means the C4 can be placed, then detonated when an enemy is near. For example, in the Multi-HillGame Mode, C4 can be placed at the entrance to the hill and detonated when an enemy tries to gain access.
